' This invention relates to a hay 5 stacker and has for its object, broadly, topro'vide a stacker consisting of few and simple parts so that it maybe manufactured economical- 5 'ly, and will be convenient in use.

the specific objects is to provide a novel means which wlll operate automatically and effectively for unloading'the fork. Another an object is toprovide means wherebyfacar- 10 rier-frame maybe readily tained ata required degree of inclination. The invention also includes a carrier frame "extension operating as a'convenience when loading the fork. 1 With theiforegoing' objects in view and others to be mentioned hereinafter the invention presents anew and u'seful construction,

jcombination and: arrangement .of'parts as descrlbed here'mand'c'lalmed, and as illustrated in the accompanying draw1ngs,1-tbeing understood that changes in formysize, p v proportion 'of p'arts" andiminorl details may be made as found to' be of advantage, said -changes being etermined by the scope of e r the invention as.claimed.- 1

In the drawings, Fig. lis a plan' view of the stacker. Fig. 2'is a side view of the same showing the fork in its lowermost position ready'for loading Fig. 3 is a plan view on an enlarged scale, being a' detail relating to Fig. Fig. 4:is a side view of the stacker showing the fork in an elevated position for *detailrelating to Fi'gs 2 ofFig. 4:.

Referring now-to the drawing for'a more particular description, in which like characs ters indicate'like parts in the several views, numeral 10 indicates a'baseframe of any 4 suitable co'n'truction adapted to sustain the weight of av carrier frame 11, an adjusting" load carried by a fork 13,."

'At-2l curedjto the inner sides, at the front. ends, of the. base-plates, and providing a pivotal mounting, indicated at 22, for the carrier-' The adjusting frame 12 consists of apair of parallellinks 23 connected and reinforced by suitable'cross-bars 24, their upper ends "being connected withithe carrier-plates 18 by hinge-members 25 their lower ends being provided with wheels or rollers 26which are 7 disposed 'on the side-plates 1 L i At ais indicated afshaft which is journalled in th'e'posts 16 adapted to be rotated" by a crank 27, and at' 28 are indicated strands or cableswhich are connectedwith the lower endaportions of the links 23,Yand it will be understood that the carrier framef maybe elevated, asmay be required, during f theoperation of building a stackjthelower ,ends'of'thelinks 23 being moved towardjthe postsj16, by rotating the shaft, i

A second inclined extensionis/provided for thecarrier-frame, this beingat its distal "end, and consisting of a pair o'f'parallel ex tension-plates 29, their inclination being 'dow'nwardly and rearwardly. The shaft 20 already mentioned, connects the endsof the plates 29, and atBO are indicated .apa-ir of stop-members 1 or hooks which are disposed at the junction of the platesl8 and 29, and have an upward and forward curvature. Numerals 31 indicate brace-strips which connect the ends ofthe extension-plates 29 with the side-plates of the carrier-frame. f

y The fork l3 includesa pair ofside-strips 32 adaptedto be disposed at the inner sides of and to move between the 'carrier-plates18 and between the extensions 21 and 29, said plates 32 being connected by suitable crossstri ps33an"d- 33*,and being provided with suitable wheels or rollers 84' for engaging the""plates 18 and-"21, and each strip 32 is provided with a horizontally disposed pin or Projection b. i r Numerals 35f indicate-comparatively short detent-m'embers or hooks which are secured to' th'effork and whichlhave a rearwa'rd curvature, and when hay; straw or similar mate-V rial has bee'n placed -'on the "fork, these hooks tend to causethe load to remain there i on while moving' upwardlyon the carrier. "1-Numerals 36' indicates; pair of controlbars for automatically changing the inclination of the fork to effect unloading, said bars being pivotally mounted at 37 upon the brace-strips 31, the outer ends of said bars being provided with detents or fingers 88 for engaging the projections b of the fork.

Sheaves or pulleys 89 and 10 are provided, respectively, for the shaft 20 of the carrier-frame extension and cross-plate 15 of the base-frame, and the fork may be moved by use of a strand or cable 41 which engages said pulleys, one of its ends being secured to the fork, and preferably to the cross-strip 33 of said fork, and any suitable power may be applied to the cable 41 for moving the load. Numerals 42 indicate a pair of guardstrips which are mounted on the outer sides of the carrier-plates 18 to provide slots 43 for receiving the control-bars 36.

Having described parts and their uses, operation will be readily understood. The fork is loaded while in the position shown in Figs. 1 and 2 of the drawings, and by use of the cable 41 may be drawn upwardly to be unloaded. When the fork approaches the top of the carrier-frame the projections 17 will engage the ends of the control-bars, and said bars together with the fork will have a swinging movement, said fork moving approximately into line with the inclined terminal extension 29 for releasing the load, the front wheels 34 of the fork engaging the stop-members or hooks 30. After the fork is unloaded it may move downwardly on the carrier-frame to the position shown in Figs. 1 and 2 of the drawings, by action of gravity.

It will be appreciated that, on account of the provision of the extension 21, the fork may be disposed in, approximately, a horizontal position for loading; the carrierframe may be elevated conveniently from time to time, while building the stack; also the sudden termination of a forward movement of the fork coincident with its rocking movement when the wheels engage the hooks 30 tends to facilitate unloading and for removal of all parts of the load from the fork to advantage.

I claim as my invention,-

6. In a stacker, a rectangular base having an extension inclined downwardly from one of its ends, a carrier-frame including a pair of connected, parallel, inclined sideplates provided with: stop-members, each side-plate having a downwardly inclined terminal extension and connected with the inclined extension of the rectangular base,

means for moving the side-plates to selected degrees of inclination relative to the rectangular base,

and a pair of control-bars a fork provided with wheels and PI'OjBC tIOIIS flHd adapted to be moved on the side-plates, "adapted to be engaged by the projec- ;tions of said fork to cause engagement thereof with said'stop-members and to dispose it approximately parallel with the inolined termin a1 extensions of the. side-plates 1 of said carrier-frame.
